I have an ajax post and in the controller I return nothing. In case there is a failure will the error message displayed with the follwoing code?

[AcceptVerbs(HttpVerbs.Post)]
    public void Edit(Model model)
    {
            model.Save();
    }

$.ajax({
             type: "POST",
             url: '<%=Url.Action("Edit","test") %>',
             data: JSON.stringify(data),
             contentType: "application/json; charset=utf-8",
             dataType: "html",
             success: function() {
             },
             error: function(request, status, error) {
                 alert("Error: " & request.responseText);
             }
         });
